Usps multi family mailbox requirements

The United States Postal Service (USPS) has specific requirements for multi-family mailboxes, also known as cluster boxes or mail centers. Here are some of the key requirements:

  1. Location: Multi-family mailboxes must be located in a secure, accessible location that is easily accessible to residents and mail carriers.
  2. Design: Mailboxes must be designed and constructed to withstand weather conditions, vandalism, and normal wear and tear. They must also be easy to clean and maintain.
  3. Size: Mailboxes must be at least 6 inches wide, 12 inches deep, and 24 inches tall.
  4. Locking mechanism: Mailboxes must have a secure locking mechanism to prevent unauthorized access. The lock must be designed to prevent tampering and must be able to withstand attempts to break or pick the lock.
  5. Key control: The USPS requires that a single key or combination be used to access all mailboxes in a cluster box. This helps to prevent unauthorized access and ensures that only authorized individuals can access the mailboxes.
  6. Mailbox identification: Each mailbox must be clearly labeled with the recipient's name and apartment number (if applicable).
  7. Capacity: Mailboxes must be designed to hold a minimum of 20 pieces of mail, including letters, flats, and packages.
